|
| The system uses six light-emitting diodes that are selectable in order from green, blue, purple, white, orange and red. |
|
| Organic light-emitting diode technology may provide a better way of generating white light with improved illumination quality over today's fluorescents. |
|
| Now, with the help of 7,000 light-emitting diodes or LEDs, the detailed work has emerged from the shadows. |
|
| Powerful light-emitting diodes have been shown to help heal wounds in laboratory animals and are now being tested on humans at the Medical College of Wisconsin. |
|
| Eyelightfish have a blunt snout, a large upturned mouth, a deeply forked caudal fin, and a light-emitting organ, called a photophore, under each eye. |
|
| Light-emitting diodes that include two-dimensional, photonic crystals have a similar structure, he notes. |
|
| Add a sprinkle of light-emitting diodes and a pinch of tiny, cuplike casings. |
|
| Other measures include replacing traditional traffic lights with light-emitting diodes. |
|
| The next step, says Hulvat, will be to produce an actual organic light-emitting diode, which glows when stimulated electrically. |
|
| Novaled AG is engaged in the research, development and commercialization of organic light-emitting diode technologies and proprietary materials. |
|
| In organic photoactive electronic devices, such as light-emitting diodes, an active organic layer is sandwiched between two electrodes. |
|
| In the impeller displacement transducing part, a switching circuit composed of a light-emitting diode and a phototransistor, etc. |
|
| Organic light-emitting diodes are organic electronic devices with an electroluminescent organic layer. |
|
| The light-emitting carbon nanotubes represent the first electrically controlled single-molecule light emitter ever constructed. |
|
| Quasiparticles like excitons may sound exotic, but getting electrons and holes together is the basis for everyday light-emitting diodes. |
|
|
|
| The idea was to replace old, incandescent lights with energy-efficient light-emitting diodes. |
|
| The light-emitting capacity of an LED is measured in megacandela or mcd. Small commercial LEDs range from 10 to about 5000 mcd. |
|
| Firefly luciferase is a 62-kDa monomeric protein found in the light-emitting organ, known as lantern, of Photinus pyralis. |
|
| In an effort to conserve energy citywide, Los Angeles Mayor Antonio Villaraigosa will announce today that traffic signals will be powered by light-emitting diodes. |
|
| Moreover, light-emitting diodes containing the highly aligned material performed better than light-emitting diodes using the disordered material, says Stupp. |
|
| That's the light-emitting diode, or LED, which is becoming increasingly prevalent in items ranging from on-off switches to taillights and traffic signals. |
|
| After a subsequent 3-day treatment within a phytotron under light-emitting diodes, there was a reduction of 44 percent to 65 percent in nitrate concentration. |
|
| The light-emitting diode produces electrolumination by semiconduction. |
|
| These lights and lenses have been changed on some vehicles from a white incandescent bulb and red lens to a red light-emitting diode and clear lens during rebuild and repair. |
|
| In the past year or so, organic light-emitting diodes have appeared in a handful of products, such as the tiny screens in some cell phones and digital cameras. |
|
| Exciton light sources may also prove useful for molecular sensing and as inexpensive alternatives to light-emitting diodes and diode lasers in optical integrated circuits. |
